Major drug interactions

Major:

dolasetron enzalutamide

Applies to: dolasetron and enzalutamide

Using dolasetron together with enzalutamide can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a relatively rare side effect.

You may be more susceptible if you have:

  • a heart condition called congenital long QT syndrome
  • other cardiac diseases
  • conduction abnormalities
  • electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting)

Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications.

You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, change in heart rate, and/or heart palpitations during treatment with these medications.

It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food/lifestyle interactions

Disease interactions

13 potential interactions Applies to: 13 conditions, including Heart Failure, Seizures, Arrhythmia, Hypokalemia, and Head Injury.

Abnormal Electrocardiogram

Major:

dolasetron

Dolasetron has a major potential interaction with Abnormal Electrocardiogram.

Dolasetron may cause acute but usually reversible and self-limiting interval changes in the electrocardiogram, including PR, QTc and JT prolongation and QRS widening. The incidence and severity of these changes are related to serum levels of the active metabolite, hydrodolasetron. Cardiovascular morbidity such as heart block and cardiac arrhythmias may occur rarely. Therapy with dolasetron should be administered cautiously in patients with or predisposed to prolongation of cardiac conduction intervals. Risk factors include hypokalemia; hypomagnesemia; use of diuretics that may induce electrolyte abnormalities; use of antiarrhythmic agents or other drugs that may cause QTc prolongation; cumulative high-dose anthracycline therapy; significant bradycardia; congestive heart failure; myocardial ischemia; and atrial fibrillation.

Arrhythmia

Major:

dolasetron

Dolasetron has a major potential interaction with Arrhythmia.

Dolasetron may cause acute but usually reversible and self-limiting interval changes in the electrocardiogram, including PR, QTc and JT prolongation and QRS widening.
